Vaccine passports should not be required for international travel as it is not yet known whether individuals who have been inoculated can pass Covid-19 to others, the World Health Organization has said.
“We as WHO are saying at this stage we would not like to see the vaccination passport as a requirement for entry or exit because we are not certain at this stage that the vaccine prevents transmission,” said WHO spokesperson Margaret Harris at a United Nations briefing on Tuesday
She also warned that vaccine passports could lead to discrimination against those who have not received a jab.
Despite such concerns, authorities in countries including the UK are considering introducing a certification scheme to show the Covid status of individuals to be used for international travel, among other settings.
Boris Johnson, UK prime minister, said on Tuesday that “so-called vaccination passports for overseas trips were likely to be “a fact of life”.
“A lot of other countries are [also] looking at that,” he said. Such certificates would also record a recent negative test or immunity as a result of a previous infection, he added.
